This might be a dumb question, but I'm currently building an HTPC and am a bit oversensitive about my components! I'm using a intel core i3-2100t processor and I just want to make sure that I don't need to apply any thermal paste with the stock cooler. Underneath the cooler, I do see 3 grey strips. The intel manual doesn't mention anything, but my MOBO manual does. I know the processor runs cool, but I want to be on the safe side.
